I have only used a sample size version of this conditioner so I don't know the long-term effects of using it but I did find it to be a very gentle conditioner. I don't necessarily look for products with all natural ingredients so that did not effect my decision in deciding not to purchase it. It advertises that it is packed with proteins, like keratin, and I often purchase products with keratin because they help to strengthen my hair. After two uses (the size of the sample) I did not notice any difference in my hair. Probably would not purchase again.
